用反引号``引起来试一下。这部分和 mysql 使用习惯应该是一致的。

麻烦举个例给我下
black-white-list:
instance:
do-dbs: [“ApolloPortalDB”,“activiti”,“ds0”,“h3-basic-setting”,“h3-customer”,“h3-orgmanager”,“h3-price”,“h3-purchase”,“h3-stock”,“h3-store”,“h3-supplier”,“h3-ware”,“h3-warehouse”] # white list of upstream schemas needs to be replicated, regular expression (starts with ~) is supported

给这个文档没啥用，我直接用名字不行，用通配符也不行 [2019/11/26 16:38:00.605 +08:00] [INFO] [mydumper.go:158] [“Thread 1 connected using MySQL connection ID 387586”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.629 +08:00] [INFO] [mydumper.go:158] [“Thread 2 connected using MySQL connection ID 387587”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.651 +08:00] [INFO] [mydumper.go:158] [“Thread 3 connected using MySQL connection ID 387588”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.675 +08:00] [INFO] [mydumper.go:158] [“Thread 4 connected using MySQL connection ID 387589”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.681 +08:00] [ERROR] [mydumper.go:164] [“Error: DB: h3-warehouse - Could not execute query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘-warehouse LIKE ‘t_warehouse_purchase_returns_order’’ at line 1”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.681 +08:00] [INFO] [mydumper.go:158] [“Non-InnoDB dump complete, unlocking tables”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.682 +08:00] [INFO] [mydumper.go:158] [“Thread 3 shutting down”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.682 +08:00] [INFO] [mydumper.go:158] [“Thread 1 shutting down”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.682 +08:00] [INFO] [mydumper.go:158] [“Thread 4 shutting down”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.682 +08:00] [INFO] [mydumper.go:158] [“Thread 2 shutting down”] [task=h3_tidb] [unit=dump] [2019/11/26 16:38:00.682 +08:00] [INFO] [mydumper.go:158] [“Finished dump at: 2019-11-26 16:38:00”] [task=h3_tidb] [unit=dump]

1）正常使用下，库表名如果带中横线，需要用返引号引起来。

2）dm 配置上，尝试用`` 引起来，另外，如果报错可以再尝试用反斜杠转义。
